Gloomy Weather Continuing Through Monday

Yesterday’s Weather

I feel like the past several days have been terribly gloomy, but I also feel like it has been like that for a while. We tend to get in these ruts in which clouds and cooler temperatures dominate the weather in an annoying tandem. I mean, yesterday’s low was hit at 2:44 PM for some perspective on how lame yesterday’s weather was.

*Dense Fog Advisory until 10 AM*

That looks like a nice doozy of a forecast, doesn’t it!?

Right back to the up and down pattern of typical Kentucky weather. Just the way I like it. It keeps you on your toes, in all actuality! I will say as an aside, the weather could be much worse. We could be in Missouri, Kansas or Oklahoma, where a significant ice storm has been impacting them over the past 24 hours.

That is a big time plus. Currently, we are dealing with some pretty terrible fog across the region. As you see above, a Dense Fog Advisory has been issued for the area, and I think that will be a common theme tomorrow morning as well. Just check out what WKU’s campus looks like:

The fog is thick this morning! h/t White Squirrel Weather

Pretty crazy. This is being caused by a pretty major inversion sitting on top of our saturated surface air. This is a similar set up to what they have to our west the ice threat. There is a shallow cold layer at the surface that was caused by a cold front marching southward. Over top of this, however, there is southerly flow in the low levels of the atmosphere. This creates a temperature inversion, where the temp a few thousand feet above the surface is warmer than the actual surface temp. The saturated air can’t mix or rise and condense, and so it condenses at the surface creating fog.

This morning’s upper air sounding from Nashville is similar to what we are seeing here. h/t SPC

This set up will be fairly common tomorrow, possibly Monday as well. We are stuck in a little bit of a rut with this current pattern, as the mid and upper level low providing the southwesterly flow in the atmosphere is moving slowly just off the California coast. This will begin to eject eastward, and bring more precipitation to the region as we head into the workweek.

Before then? We are still looking at rain today, some of which could be pretty heavy. This will be associated with a weak shortwave in the lower levels of the atmosphere, in addition to the plentiful moisture already in place. Anticipate the rainfall to move into the region around noon, and to last much of the afternoon.

Tonight, the precipitation moves out, but a similar set up develops. We look to have an inversion on top of a saturated, or near saturated surface layer. This will likely create more fog as you wake up for Church or other Sunday activities. Highs both today and tomorrow will be pretty marginal, with clouds locking us in.

By Monday, though, the shortwave trough over California has been ejected eastward, creating a surface low to our west. This looks to move to our northwest, carrying with it a nice warm front. That looks to move through at some point on Monday, warming temperatures into the 60s by the afternoon hours.

Rain looks to hold off until late Monday night and into Tuesday. The cold front will likely move through on Tuesday, and I think there could be an isolated storm or two along that front.
